Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed June 25, 1914. Serial No. 847,244.

To all whom it may concern:

Be it known that I, WILLIAM I. RAVERT, a citizen of the United States,residing at Hazleton, in the county of Luzerne and State ofPennsylvania, have invented a new and useful Fraud-Preventive Means forCoin-Controlled Apparatus, of which the following is a specification.

This invention has reference to improvements in fraud-preventive meansfor coincontrolled apparatus, and its object is to provide mechanism inthe path of a coin traveling to the operating mechanism of acoin-controlled apparatus, which mechanism will direct a proper coin tothe coin-controlled apparatus, but which will divert any other article,whether a coin or slug or other device, once introduced into theapparatus, so as to be returned to the person introducing it.

Since most check or coin-controlled apparatus are designed to beoperated by a five cent piece, it will be considered that the propercoin for operating the apparatus is a five cent piece, although it ispossible to use other coins with a properly designed apparatus, since afive cent piece and other coins have certain characteristics in common,although differing in other characteristics, which permit the adaptationof the invention to any coin.

A five cent piece is made of a nickel composition, and therefore thecoin has a certain weight. The coin also has a certain rim thickness anda certain diameter and within the rim the two faces of the coin aredepressed, the rim also being of a certain radial extent.

The great majority of devices used for the purpose of fraudulentlyoperating coincontrolled machines lack one or more of thecharacteristics of a genuine coin, and as all of such characteristicsmust be substantially present in order to direct an introduced coin tothe lock controlling mechanism of the vending machine,thefraudpreventive structure will refuse any slug or like device withwhich it may be attempted to operate the vending side of the machine.

Considering the courseof a coin from the point of introduction until ithas successfully passed the fraud-preventive devices, or, if notacceptable to the machine, has been returned to the user, the firstthing in order is the entering aperture, and in the present instancethis is so proportioned as to refuse to receive any coin of even a smallfraction of an inch greater diameter than a proper coin. In accordancewith the present invention the coin or other article if not too large isplaced in an operating member of the machine which is to be manipulatedby the user and is carried thereby into position to then travel to otherparts of the device, but if a slug or similar article introduced throughthe usual coin receiving aperture or slot and be moved out of sight bythe manipulating member be too thick it will simply return again intosight on the return of the manipulating member to its first position,and must be removed before the ma chine can operate at all. The firstdiscarding device of the fraud-preventive structure,

therefore, depends upon size, since an article of too great diametercannot be introduced into the machine, and if too thick even to a slightdegree will not travel farther into the machine, but will be returned tothe person introducing it.

A coin or slug which is neither of too great diameter nor too thickpasses on to the next testing mechanism, which relies for its actionupon the presence of a. laterally out-' standing rim found on allgenuine coins and some slugs sometimes used to fraudulently operate thevending machine. If such a rim be absent the article is at oncediscarded and returned to the user. Should the rim, however, be present,the coin or fraudulent slug, as the case may be, is directed into theproper course to be subjectedto other testing structures, which in thepresent instance do or do not respond to the weight of thefgenuine 0rspurious device, as the case may be.

Since all genuine coins of the five cent type are made of a nickelcomposition, they have a different weight from a slug otherwisesimulating the coin, but made of some other material. The weighingapparatus, therefore, is made very delicately responsive to a coin ofproper weight, but will refuse to act under a coin of less than theproper weight, even though the difference be but a. very small fractionof the weight.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawings forming a part of this specification, with thefurther understanding that while the drawings show a practical form ofthe invention, the latter is not confined to any strict conformity .Withthe showing of the drawings, but may be changed and modified so'long assuch changes and modifications mark no material departure from thesalient features of the invention.

In the drawings, Figure 1 is an elevation of the fraud-preventive devicewith a portion of a casing assumed to be that of the vending machineshown in section. Fig. 1 is a view of a portion of the structure of Fig.1 omitted from the left hand side thereof. Fig. 2 is an elevation of thestructure of Fig. 1 as viewed from the left hand side, with some partsin section, on the line 22 of Fig. 1. Fig. 3 is a section on the line 33of Fig. 1. Fig. 4 is a section on the line 44 of Fig. 1. Fig. 5 is asection on the line 55 of Fig. 2, but showing the parts in a differentoperative position. Fig. 6 is a fragmentary perspective view of aportion of the structure. Fig. 7 is an elevation of the structure ofFig. 1 omitting some parts and showing the face of the structure remotefrom that viewed in Fig. 1. Fig. 8 is a section on the line 8-8 of Fig.1 with some parts otherwise cut by the section shown in elevation. Fig.9 is a fragmentary section on the line 99 of Fig. 4.

In the drawings there is shown a casing 1 which may if needed be made ofan appropriate number of parts suit-ably assembled to permit manufactureand the introduction of certain parts into the casing.

Considering the structure as in the position it assumes when properlyinstalled, the upper part of the casing is provided with an elongatedpassageway 2 substantially horizontal and of a depth from front to rearsufficient to receive a plate-like slide 3 having an arm 4 extending inthe same direction as the length of the passageway 2 and terminating ina manipulating head 5 which in the particular structure shown is similarin shape to a spear head, this forming a convenient means for theapplication of the fingers of the human hand for moving the slide 3lengthwise of the passageway 2, while the latter has at the end throughwhich the arm 4 and head 5 project a lower ledge continuation 6 for apurpose which will presently appear.

The casing or body member 1 of the structure is formed with a bracketcontinuation 7 at the end remote from the ledge 6 and extendinglengthwise along the bracket 7 is a slot 8 continued for .an appropriatedistance into the corresponding wall bordering the passageway 2.

Formed in .both upright walls of the passageway 2 are upright slots 9,9*, respectively, the slot 9 being close to the inner ter mination ofthe slot 8.

The slide 3 is provided with a chamber or passage 10 opening at thelower edge of the slide, and at a higher point the walls of the slideare pierced by openings 11, 12, respectively, in alinement laterally ofthe slide, and both communicating directly with the passage 10.

The opening 11 is made circular and is for convenience placed on theright hand side of the slide as viewed from the end provided with thearm 4. The opening 11 is of a diameter to snugly yet freely receive afive cent piece. the machine being considered as adapted for such coin.The opening or aperture 12 is made of slightly less diameter so that acoin properly introducable through the opening 11 cannot be introducedthrough the opening 12. Such coin will be arrested by the walls of thepassage 10 surrounding the opening 12 and directed into the passage 10by gravity. The thickness of the passage 10 between its side walls issuch as to snugly yet freely receive a coin of proper value, such as afive cent piece.

In the normal condition of the parts the two openings or apertures 11and 12 are exposed beyond the corresponding end of the passageway 2, butthe passage 10 is underridden by the ledge 6, so that a coin introducedinto the passage 10 will drop upon the ledge 6 and there remain and onthe movement of the slide 3 into the passageway 2 for a purpose whichwill hereinafterappear, the coin will move with the slide resting uponthe bottom wall of the passageway 2.

That end of the slide 3 remote from the arm 4 is provided with anotherarm 13 normally within the passage 2 and slowly rising away from theslide 3 to which it is connected near the lower end of the latter. Theedges of the arm 13 are parallel one to the other and the arm is of suchlength and inclination that it terminates just under a flange 14 on theupper edge of the bracket 7 and forming a continuation of the upper wallof the passageway 2. The arm 13 at its free end has a continuation 15underriding the flange 14 and carrying a pin 16 projecting throughtheslot 8, and beyond what may be termed the rear face of the casing 1having a grooved end 17 engaged by one end of a continuation 18 of aspring 19, the latter being made fast to the rear face of the easing 1by a clip 20 or otherwise.

Extending through the slots 9 and 9 in the front and rear walls of thepassageway 2 is a head portion 21 of a flat bar 22 disposed on what maybe termed the front face of the casing 1 and capable of sliding up anddown in front thereof, the bar being substantially upright. At the lowerend the bar passes through and is guided by a bracket 23 projecting froman appropriate portion of the casing 1 and having a return portion 24 sothat the bar 22 is partially embraced by the bracket 23, the bar havinga limited movement toward and from the easing while always held andguided by the bracket 23. l

The head end 21 of the bar 22 is formed with a slot 25 through whichthearm 13 passes, so that when the slide 3 is reciprocated, the bar 22is given a lengthwise movement because of the cam action of the inclinedarm 13. Ordinarily the slide 13 is at the extreme limit of its movementtoward the left as viewed in Fig. 1, and this may be termed the initialor inoperative position, while the upper end of the arm 13 thentraverses the slot and the bar 22 is at the uppermost limit of itsmovement through the slots 9 and 9.

At the lower end the bar 22 is formed near the outer edge with alongitudinally projecting finger 26 and a laterally pro jecting toe 27on the other edge toward the casing 1, and the corresponding face of thecasing adjacent to the point the toe 27 occupies when at the highestlimit of travel of the bar is recessed, as indicated at 28, so thatunder circumstances to be hereinafter referred to the toe 27 may lodgein the recess 28 to thereby lock the bar 22 against longitudinalmovement, and especially a lowering movement.

The interior of the casing below the passageway 2 is formed with alaterally'diverted coin chute 29 having an upper end 30 adjacent to theslots 9 and 9*, but to the left of them as viewed in Fig. 5. WVhL-n theslide 3 is moved to the full extent of its travel in the activedirection, this extent being determined by the engagement of the slidewith the head 21, the coin passage 10 is then in coincidence with theopening 30 of the chute 29. This chute is laterally diverted toward theright as viewed in Fig. 5,

but with a declination that terminates in a substantially verticaldownward portion 31, at the lower end of which the respective front andrear walls of the casing are formed with laterally extended slots 32, 33made somewhat longer than the width of the coin chute. Below the slots32, 33 there is within the casing a laterally expanded chamber 34slightly deeper from front to rear than the thickness of any coin orslug which may reach it, and this chamber continues downwardly into adiscard passageway 35 and another passageway 36 separated by an uprightwall 37 having a beveled upper edge 38 directed toward the discardpassageway 35.

What may be termed the rear wall of the passage 36 is continueddownwardly and to the right as viewed in Fig. 5 as shown at 39, whilethe front wall is cut away to form a recess 40. At the lower end of thecontinuation 39 there is provided a short chute 41 having an inclinedtop or cover portion 42, and a side opening 43 stopping short of thebottom of the chute to provide an arresting ledge 44 for a purpose whichwill presently appear.

The wall 37 forming the division wall between the passageways 35 and 36is widened at its lower end to provide a ledge 45 on the side remotefrom the discard passageway 35.

The recess 40 is provided for the reception of a scale pan 46 havingparallel side walls 47 which may be somewhat higher than the diameter ofa coin of proper value, and the pan is provided with an inclined bottomportion 48 which when the pan is elevated to its highest point is inposition to discharge upon the cover or ledge 42 of the passage 41,which ledge is inclined in the same direction as the bottom 48 and isarranged to deliver into one side of a discard trough 49 which in turnmay be continued in the downward direction to any suitable point, and isshown in Fig. 1 as extending through what may be considered the front ofa casing 50 assumed to inclose the entire machine, the trough openinginto a pan or receptacle 51 from which a discarded article may bereadily removed, since it is freely accessible from the exterior of theapparatus. In order that any coin or other article re ceived upon thescale pan 46 and finding its way upon the ledge 42 and from thence maybe positively directed into the discard trough, the ledge 42 is flankedon the outer side by a deflector plate 52 of appropriate shape.

The scale pan 46 is pendently hung by trunnions 53 to a double scalebeam 54, one part being to the front of the casing 1 and the other tothe rear thereof, and both mounted upon alined pivots 55. The trunnion53 connecting the scale pan to the part of the scale beam to the rear ofthe casing 1 ex tends through an appropriately, curved slot 56 in theextension 39. Those ends of the two-part scale beam remote from the panare joined by a yoke 57 carrying a weight 58 held thereto by anelongated set screw 59 extending through both the weight and the yokeand held in any suitable adjusted position by a lock nut 60, the setscrew not only serving to hold the weight in place, but providing adelicate eounterpoise for the scale beam by which it may be veryaccurately adjusted to respond to coins of suitable weight, the lock nut60 serving to fix the adjustment against accidental displacement.

In order to maintain the scale pan 46 in proper position, an equalizinglink 61 is pivotally connected at one end by a staple 62 to the bottomof the'scale pan, and at the other end by a staple 63 to an appropriatefixed portion of the casing 1, the link 61 being arranged in parallelismwith the scale beam and freely moving therewith and also having anintermediate bend indicated at 64 to carry it out of the path of anycoins dropping through the discard chute section 35.

Should a coin or slug ultimately reach the scale pan 46, and all propercoins and slugs possessing certain characteristics do,

- certain structures to be described are provided for causing such coinsand slugs to move into the scale pan without shock or jar thereto, sothat there is no disturbing momentum to interfere with accurateweighing. All proper coins reaching the scale pan depress the latteragainst the resistance of the weight 58 until the pan is arrested byengagement with the ledge 44, when the inclination of the bottom portion48 of the pan causes the coin to roll off by gravity into the chute 41,by which it is directed into another chute 65 conveying the coin to thecoin-controlled apparatus which may be of any suitable type operable bya coin of proper characteristics. Such a coin-controlled apparatus doesnotin itself form any part of the present invention, nor is the presentinvention limited in its use to any particular type of coin-controlledapparatus, wherefore such apparatus is neither shown nor described inthis application.

If the coin reaching the scale pan be of light weight, or be a spuriousarticle having such characteristics as will pass the fraud preventingdevices up to the weighing structures, such a spurious article will befound almost without exception to be of light weight as compared to agenuine coin of proper value. Such a spurious article will,therefore,.fail to depress the scale pan and will simply roll along theinclined bottom thereof on to the inclined ledge 42 to be directed bythe latter into the discard trough 4S) and so delivered at the front ofthe machine to the operator.

The delicacy of the weighing apparatus is maintained by having it quiteseparate from the coin chute with the sides arranged to have no sensibleretarding effect upon the coin or slug.

The walls of the passageway 36 are brought closer together wheredischarging into the scale pan 46 than are the walls of the scale pan,so that there is no chance of the coin catching upon the edgesof thescale pan to interfere with the movement of the coin or slug into thescale pan.

The slot 33 is elongated at the ends on the rear face of the casing bychannels 66 to receive a shaft 67 having bearings in brackets 68, 69,respectively, the bracket 68 being made fastto one edge' of the casingand the bracket 69 at the opposite edge thereof, and both bracketsprojecting beyond the front face of the casing for a purpose to bedescribed.

Near one end of the slot 33 the shaft 67 carries a relatively broadroller 70 and near the other end of the same slot the shaft 67 carries arelatively narrow roller 71, these rollers being spaced apart less thanthe diameter of a proper coin. Mounted to move into and out of the otherslot 32 are rollers 72, 73, corresponding to the rollers 7 O and 71 inwidth, spacing and position, the roller 72 being in coactive relation tothe roller 7 O and the roller 73 being in coactive relation to theroller 71. The rollers 72 and 73 are mounted or formed on a short shaft74 having bearings in legs 75 of a yoke member 76, the yoke portion ofthe yoke member being quite wide and terminating at the edge remote fromthe legs 75 in ears 77 mounted to rock upon a pivot pin 78 carried by abracket 79 fastto the corresponding face of the casing 1, this being thefront face. The shaft 74 with its rollers 72 and 73 may, therefore, berocked about the pin 78 as a pivot support, the rocking being toward andfrom the rollers 70 and 71, and the extent of rocking being sufficientto cause the rollers 72 and 73 to enter the coin chute to a sulficientextent to grip a coin or other article between the pairs of rollers. Atthe upper edge of the yoke 76 there is formed an outstanding eye 80 fora purpose to be described.

'The brackets 68 and 69 outstand from the front of the casing 1 for anappropriate distance and journaled in these brackets is a rock shaft 81extending from one bracket to the other, and for a short distance beyondthe bracket 69 where the shaft is made fast in a hub 82 on one end of arock arm 83 formed or provided at the other end with an arc-shaped rackbar 84 having the teeth directed toward the axis of rocking of the arm83.

Mounted upon the end of the shaft 67 adjacent to the bracket 69 arepinions 85 and 86, the pinion 85 being in constant mesh with the rack84. Between the two pinions there is loosely mounted upon the shaft 67 aratchet. wheel 87 carrying pawls 88 in position to engage the pinion 86for one way rotation of the ratchetwheel, the pawls riding idly over thepinion 86 on the rotation of the pinion in the opposite direction. Inoperative relation to the ratchet wheel is an anchor escapement 89having a pendulum continuation 90, the escapement being mounted forrocking movements upon a pin 91 carried by the bracket 69.

The rock arm 83 is urged constantly in one direction by one end of aspring 92 which is coiled about the hub 82, and has its other end heldby a stud 93 fast to the bracket 69, the tendency of the spring being tomove the arm upwardly in the installed position of the structure againstthe part or stop 24.

The bar 22 is so arranged as to move in close relation to that face ofthe arm 83 remote from the bracket (39, and on the arm 83 there is pin94 in position to engage the lower end of the bar 22 between the finger20 and the toe 27. When the bar 22 is moved downwardly by an inwardmovement of the slide 3 the pin 94 is engaged by the bar 22 and the arm83 is rocked against the tendency of the spring 92 and the shaft 67 isrotated by the engagement of the rack bar 84 with the pinion 85. Thismovement, however, is inactive to the anchor escapement mechanism, sincesuch movement causes the pinion 86 to ride idly under the pawl 88.

The shaft 81 is provided with three arms 95, 96 and 97, each shown asprovided with a hub portion mounted on the shaft and made fast theretoby a set screw 98. \Vhile this provides for the adjustment of the armsupon the shaft, such adjustment is not necessary, since the arms may beformed as fixtures upon the shaft.

The arm 95 terminates in an angle extremity 98 movable into engagementwith a stop finger 99 pi 'otally mounted upon a stud 100 carried by thecasing 1, the finger rocking freely on the stud and the end 98 of thearm 95 being movable into and out of engagement with the finger near thepivoted end. This finger is arched to avoid engagement with other partsof the mechanism, and is appropriately bent to provide a free extremity100 entering the space designed for the reception of the scale pan 46and normally occupied thereby, the finger being so situated that itsfree extremity moves easily into and out of the interior of the raisedscale pan tl'irough the upper end thereof, being guided by a recess 101in the casing adjacent to the passage 38. The free extremity of thefinger is beveled, as indicated at 102, for a purpose to be described.Under ordinary inactive conditions the finger 99 is raised by theengagement therewith of the end 98 of the arm 95, so that the beveledextremity 102 of the finger is just within the guiding recess 101 inposition to drop by gravity into the scale pan when released by the arm95. A pin 103 in the path of the finger 99 limits its movement into thescale pan after released by the arm 95.

The arm 96 is a double arm having two opposed claws 104 and 105, each ofwhich is movable into engagement with the eye 80, and these claws arearranged eccentrically to the axis of rocking of the arm 90, whichextends 011 both sides of the shaft 81, that on the engagement of eitherclaw with the eye 80 the yoke member 76, and with it the shaft 74, arerocked away from the shaft 67. The yoke member 76 is normallyconstrained toward the shaft 67 by a spring 106 fast at one end to thecasing 1 and at the other end bearing against the shaft 74 which may beintermediately reduced, so that the spring will prevent any rocking ofthe yoke member in'its bearings, and thus maintain the rollers 72, and7173 in proper relation. To provide a good bearing surface for thespring and to provide for any lengthwise rocking of the shaft 74 topermit accommodation of the rollers to the margin and intermediateportions of a rimmed coin or slug, the spring 106 has its free extremitysplit, as shown at 107. so as to engage the shaft at different points,the bearings of the shaft 74 being made sufficiently loose to admit ofsuch rocking movement.

The arm 97 is designed to operate a coin arresting mechanism. Thismechanism comprises a rock lever 108 shown in Figs. 1, 6 and 8. Thislever is mounted on a pivot pin or screw 109 around which there iscoiled a spring 110 with one end fast to the pivot pin and one endbearing against the lever to normally constrain it to one limit of itsmovement. The ends of the lever are bent into angular relation tothelength of the lever to constitute angle pins 111 and' 112. The lever ispivoted on the front face of the casing 1 and the fingers 111 and 112extend through curved slots 113 and 114 extending through the casing 1.from front to rear. These slots are curved about the axis of the pivotpin 109 as a center. The slot 113 enters the end 31 ,of the chute 29 andthe slot 111 enters the passage 34, so that the finger 111 may be movedinto and out of the path of a coin traveling along the chute 29 into theend 31 thereof. and the end or finger 112 may be moved into the path ofa coin traveling between the rollers 71 and 73. The result of this isthat when the lever 108 is in its normal position of rest, the finger111 is in the path of a coin approaching the rollers 70to 73, and whenit is rocked in the other direction the finger 111 is moved out of thepath of such a coin and the finger 112 is moved into the path of such acoin, to again move out of the path of the coin when the lever 108returns to its first position under the action of the spring 110.

That end of the lever 108 carrying the finger 112 is bent at an angle tothe length of the lever, and this bent portion is shown at 115. On thestraight portion of the same arm of the lever having the bent extension115 is an outstanding wing 116, which. when the lever is in its normalposition. is situated at an angle to an angle member-117 at the outerend of the arm 97. WVhen the arm is rocked by a corresponding rocking ofthe shaft 81 theextremity 117 is brought into engagement with the wing116 then at an angle to the pathof travel of the extremity 117, and thisWing being to one side -spring 1l0, the extremity 117 finally movinginto parallelism with the outer face of the wing 116, and therebylocking the lever against return movement under the action of the spring110. When the shaft 81 rocks back to its first position, the lever 108is released after the shaft has accomplished a portion of its returnmovement, so that the lever 108 .will again move to the first positionunder the action of the spring 110.

The casing 1 may be made in mostpart of a single casting with only suchportions removable as may be necessary for the introduction of some ofthe other parts, or the whole casing may be formed in a single castingif such be desired. \Vherever necessary brackets 118 are providedwhereby the structure is made fast to the casing 50 or other support,and these brackets may or may not be made in one piece with the casing,these being matters of manufacture and convenience. The brackets 68 and69 are shown as formed separately from the casing and attached theretoby means of other brackets 119, 120, but even these parts may ifconvenient, be made in one piece with the casing, these being alsomatters'of manufacture and convenience.

The scale beam 54 may have its pivots 55 of the customary pointed screwtype engaging studs 121 projecting from opposite sides of the casing 1at an appropriate point, and best shown in Figs. 2 and 3, it being alsocustomary to provide lock nuts 122 for the pointed screws.

The shaft 81 may be conveniently mounted by providing the hub 82 with areduced portion 123 to be mounted in acorresponding journal opening inthe bracket 69. The portion 123 has a radial pin 124 projectingtherefrom and the bracket has, a slot leading from its outer end intothe bearing for the reduced portion 123. This slot is of a widthsufficient to permit the passage of the shaft, but not of the reducedhub portion 123. The other end of the shaft has a reduced portion 126adapted to journal in the bracket 168. The shaft is moved through theslot 125 until the portion 123 is coincident with its bearing in thebracket 69, and then by moving the shaft lengthwise so that the pin 124Wlll pass transversely through the slot the end 126 of the shaft isseated in its bearing in the bracket 68 and the reduced portion 123seats in the bracket 69. Then on turning the shaft 81 into position tobring the arms 95, 96 and 97 into operative relainvention willautomatically refuse to direct either a genuine coin or a counterfeitcoin, or a slug or any other article which does not substantiallyduplicate a practically unworn genuine coin of the proper denominationfor which the vending side of the machine may be set.;

To make a fraud preventive device efi'ectiv it must be made to meet, 'sofar as it is possible, all conditions which might permit the fraudulentoperation of the vending side of the machine. Furthermore, in order tomeet the various conditions which might permit the fraudulent operationof the machine, the preventive device must at least in some parts bedelicately responsive, and consequently delicately constructed andadjusted, wherefore it is necessary to prevent the introduction into,the machine of any article liable to clog or injure the machine, forcertainty of operation is import-ant. Entering slots at the intakemouths of coin chutes do not prevent the forceful introduction ofcertain articles which might clog the machine, or do not certainly avoida fraudulent operation of the machine by long pieces of Wire or thelike. To avoid such a contingency the present invention protects theinitial parts of the fraud-preventive device by the employment of aplunger receptive mechanism into which the coin or slug or the likeisplaced, and by which said coin or the like is moved to a point Where itmay find entrance into the coin chute, the latter being wholly protectedby the plunger from access by anything but an article simulating a coinor slug.

The opening 11 may be of a diameter but one or two thousandths of aninch larger than the diameter of a genuine coin of proper denomination.This prevents the introduction of slugs or like articles of over sizeand limits the intended fraudulent operator to articles of the samediameter, or of less diameter than a genuine coin. Moreover, the frontto rear depth of the passage 10 is made to closely approach withina'very few thousandths of an inch to the rim thickness of a coin ofproper denomination. If it be attempted to place in the slide afraudulent article of either suitable diameter or of less diameter, butof somewhat greater thickness than a genuine coin, such an article maybe deposited in the slide and may be moved into the passageway 2 whenthe slide is pushed thereinto but the frictional engagement of such anarticle with the front and rear walls of the passage 10 will prevent thearticle from dropping into the that the fraudulent article is broughtback into sight by the return movement of the slide. The distance fromthe opening '11 to the bottom of the slide is less than the diameter ofthe opening 11, so that the returned fraudulent article is visible tothe operator, thus apprising the operator that the machine will notreceive such an article, and if the article be left in the slide, asubsequent" honest operator may readily remove the fraudulent articlebecause-of the presence of the opening 12 by means of which the articlemay be readily grasped by the fingers and lifted out of the slide.

Suppose'that it be attempted to operate the machine by means of a thindisk or slug of either suitable diameter or of smaller diameter than thesuitable diameter. Such a disk may be readily introduced into the slide,and on pushing the latter into the passageway 2 the disk will drop intothe chute 29 and gravitate along the latter until it reaches the rollers70 to 73, the finger 111 having in the meantime been moved out of thepath of such disk, but the disk being of large enough diameter isarrested by the finger 112 then below the rollers. On the return of theparts to the normal position the disk, which is urged toward the discardchute 35 by the finger 112, may be grasped between the rollers if nottoo thin, and will be fed straight downwardly thereby, but if too thinto be grasped by the rollers, will simply fall through them whenreleased by the finger 112. The edge 38 being on that side of themid-point between the rollers of each pair remote from the discard chute35, engages the disk to the corresponding side of its center,

and thus directs it into the discard from which the disk gravitates intothe trough 19, and rolls down the trough into the receptacle 51, thusapprising the operator that the machine has refused to receive the disk.If such disk be of sufliciently small diameter, it will not be stoppedby the finger 112, but at once drop into the discard chute, and fromthence into the trough 10. Suppose, however, that the slug introducedinto the machine be of the same diameter as a genuine coin and of thesame thickness, but is smooth faced, that is, there be no rim present.Under such circumstances the slug will enter the chute 29 on themovement of the slide 3 into coincidence therewith, and will enterbetween and be grasped by the rollers 70 to 73,

' and ultimately be arrested by the finger 112.

()n the return of the slide to its first position the rollers arerotated in a direction to feed the disk downwardly. but the rollerssimply feed the disk straight downward and the finger 112 tends todivert the disk into the discard chute this being assisted by thebeveled upper end 38 of the division wall 37,

bly of proper weight, is directed, because ofits plane faces, into thediscard. However, such washers or slugs are usually of lighter weightthan a genuine coin, and should such a Washer or slug because of thepossible presence of a bur about 'its edge formed in the stamping of theslug be diverted into the passage 36, it .will still be discardedbecause of its under weight, as will presently appear.

There; are in existence large numbers of tokens quite similar toan'ordinary five cent piece, and employed in some sections of the UnitedStates for trade purposes. touch tokens havemarginal rims and sunkenfaces and are often of the same diameter and thickness at the rim as agenuine I "e cent coin. Should such a token be introduced into themachine even with honest intent, it will still be refused, because suchtokens, although simulating in all other respects a genuine coin forwhich the machine may be set, are

almost invariably of lighter weight. If it be tion of the parts therollers have been separated by the movement of the claw 101 of the arm96 into the eye 80, thus rocking the yoke 76 in a direction'to move therollers 72 and 7 3 out of the path'of the coin.

The parts are so timed in operation that the claw 101 is moved outof theeye 80, there- I by releasing the rollers '72 and 73 to move under theaction of the spring 106 into engagement with the token then restingupon the finger 112. As soon as this is accomplished the arm 97 releasesthe lever 108, having in the meantime held the latter inactive by theengagement of the end 117 with the wing 116. Since the lever 108 is thenfreeto be rocked by the spring 110, the finger 112 is moved out of thepath of the token held by the rollers engaging it, the rollers 70 and 72being wide enough to remain in engagement with the rim of the token,while the rollers 71 and 7 3 engage the depressed faces of the tokeninside of the rim, since these lastnamedrollers are narrow and are sospaced from the broader roller-s as to thus engage the token.

The narrow rollers 71 and 73 will not readily ride over the raisedmarginal rims on opposite sides of the token, but the wider rollersquickly pass along the rim, with the result that the token is rockedupon the rollers 71 and 73 as an axis, and when relieved from therollers and 72 quickly swings so as to be on the side of the wall 37toward the chute continuation 36, and when finally releasedby therollers 71 and 73 the token gravitates into the chute continuation 36.The release of the token from the rollers 71 and 73 is accomplished bythe entrance of the claw 115 into the eye 80, thus pulling the roller 73away from the roller 71 and out of engagement with the token. However,while these'operations have taken place, the end 100 of the finger 99-has entered the scale pan 46, which at this time is in the elevatedposition, and in part coincident with the passage 36. The token onleaving the rollers 71 and 73 drops on to the ledge 45 against which itis held by the beveled end 102 of the finger 99, the'token being partlyon the ledge and partly in the scale pan. Now, as the partsmove to thefull initial position, the return movement having been retarded by thependulum 90 and escapenient controlledv thereby, so that the returnmovement isv relatively quite slow,'the end 98 of the arm 95 finallyengages the finger 99 and raises it out of the path of the token,whereupon the latter being free to roll along the inclined bottom of thescale pan fully enters the latter, but being of insufficient weight tooverbalance the scale, simply rolls along the scale pan and out of theopen end thereof on to the ledge 42 to be directed by the guard 52 intothe trough 49, and is directed to the outside of the machine for returnto the operator, thus apprising the latter that the token employed isrefused by the machine.

That portion of the casing corresponding to the chute :29 is providedwith sight openings 127 along the course of the chute 29 to indicate thelodging of any obstructive matter, should such enter the machine.

As it is possible that the scale pan may stick inthe lowered position,in which position the weighted end of the scale beam 54 would be in thepath of the lower portion of the free end of'the arm 83, a camprojection 128 is there provided to move the scale pan out of the wayand to its normal position on the return of the arm 83 to its normalposition.

Suppose that the operator introduces into the machine a genuine coin ofthe proper denomination, and not worn smooth, or not so worn as to be oflight weight, for even genuine coins worn smooth or of too light weightarereturned to the operator in the same manner as smooth slugs orwashers, or light weight slugs otherwise simulating genuine coins. Sucha coin finds its way into the chute 29 as before, and between therollers, and is swung by the rollers 71 and 73 into position to moveinto the chute continmemes uation 3G,,and is finally arrested by the end102 of the finger 99 and by the ledge 45 ready to move into the scalepan. Since the return movement of the parts to the normal position isrelatively slow, the finger 99 is moved out of the scale pan with a likeslow movement, so that the coin rolls into the scale pan deliberatelyand without any shock or jar thereto. Before the end 102 of the finger99 has moved out of the scale pan sufliciently to Wholly release thecoin, the latter being of greater weight than the counterweight 58,causes the scale pan to drop, so that by the time the coin iswhollyreleased by the finger 99 the upper end of the ledge 42 is in the pathof the coin, thus preventing its escape from the scale pan until thelatter has dropped to the ledge 44, whereupon the coin rolls into thepassage 41 and ultimately into the chute 65 by which it is directed tothe vending side of the apparatus.

Brass and steel from which most five cent and higher denomination slugsare made, are both lighter than either nickel or silver, whereforeotherwise exact duplicates of the genuine coins would be of lighterweight than genuine coins so that the scale is the final test of thegenuineness or spuriousness of the article employed to operate the ma- 9chine, and the scale is susceptible of very accurate adjustment. To makea brass or steel slug as heavy as a genuine coin, but no larger indiameter or thickness, such slug must either be flat or have a rim ofmuch greater width than that of a genuine coin. Under such circumstancesthe slug if fiat will be discarded, or if the rim be of the necessarilygreat radial extent, the rollers 71 and 73 will engage the rim itselfinstead of engaging the face of the slug inside of the rim, thus movingthe slug directly into the discard chute the same as though it weresmooth throughout whether or not it be of the same weight as a genuinecoin. The coin or slug reaching the scale pan moves thereupon slowly andis held there for an appreciable time, so that the scale may be adjustedin a manner to cause a very small difference in weight to make itrespond to a genuine coin, but direct a spurious article or a lightweight coin into the discard chute.

Since all improper devices which may be introduced into the machine arereturned to the operator, any one who through carelessness or ignoranceintroduces a more valuable coin into the machine, such, for instance, asa ten cent silver piece, will have it returned without the operation ofthe machine, so that no loss is experienced through such carelessness.Should by any means a second coin be introduced into the machine beforethe first coin has moved out of the way by the rollers propelling it,the finger 111 which in the normal position of the parts is within theend 31 of the chute 29, will act as an arresting means for such secondcoin. Should the attempt be made to push in the slide a second timebefore the parts have returned to their normal poition, since the slidemoves outwardly much more quickly than the parts first actuated therebyreturn to their normal position, a second actuation of the slide isprevented by the engagement of the toe 27 in the recess 28 because ofthe manner in which'the bar 22 is hung, causing the toe to swing intosuch position. It is only when the arm 83 has returned to its fullupward position that the arm 22 being engaged by the pin 94, is swung sothat the toe 27 is outside of the recess 28, thereby unlocking the slide3.
